IPC: F16C19/18
Filed: 1959-12-09
Abstract: 891,666. Ball bearings. H.M.C. WHEELS Ltd. Sept. 15, 1960 [Dec. 9, 1959], No. 41916/59. Class 12 (1). A double-row ball bearing comprises outer and inner sleeves of unground case-hardened metal which have axially spaced ball-ways and balls therebetween. In an embodiment, annular spaces 11 are formed in the outer sleeve 1, Fig. 1, and the inner sleeve includes a middle portion 5 and two end portions 4 which are held together by a tubular liner 6 having ends 7 upset so as to engage chamfered surfaces on the portions 4. The annular spaces 11 contain lubricating grease and are sealed by sealing rings 12 held by spring retainers 13. The spaces 11 also facilitate assembly, the balls being received by the ballways prior to the fixing of the end portions 4. The outer race 1 is knurled at 9 to allow it to be force-fitted into a hole in a wheel for example. A clearance is provided between the outer and inner sleeves. In a further embodiment, the inner sleeve includes two portions 14, 15, Fig. 2, each having an end 17 of increased diameter. In other embodiments, not shown, the portions 14, 15 are separated by a spacing ring, and the annular spacers 11 are reduced, or completely filled, by radially extending the ends of the outer or inner faces.

Title: Device for spacing objects on a conveyor
IPC: B65G47/28
Filed: 1965-10-05
Abstract: 1,119,122. Conveyers. E. P. REMY ET CIE. 5 Oct., 1965 [5 Oct., 1964; 25 Nov., 1964], No. 42114/65. Heading B8A. Objects C1, C2 on a chain-driven roller conveyer 5 are spaced by means of dogs 8, 9, 10 on endless chains 1a, 1b. The conveyer 5 conveys the objects at a speed V until the first object C1 is slowed by the dog 8a moving at a speed V<SP>1</SP> less than V. The object C1 is then pushed laterally towards the chain 1a by the dog 8b also moving at the lower speed V<SP>1</SP>. As the object C2 is moved abreast of the dog 10a on the chain 1a, the object is pushed laterally towards the chain 1b. At the end of its movement parallel to the conveyer 5, the dog Sa frees the object C1 which resumes its original higher speed V. The object C2 now moves into engagement with the dog 8b, is slowed thereby and is spaced from the object C1. Constructional details, Fig. 3.-The chains 1a, 1b are carried on sprockets 2a, 2<SP>1</SP>a, 2b, 2<SP>1</SP>b which are mounted on parallel linkages 6a, 6b and beams 14a, 14b, the linkages being adjustable to vary the spacing of the beams. The dogs are detachably mounted on the chains 1a, 1b and are provided with rollers 11a which are guided by the beams 14a, 14b and by members 15a, 15b attached to the beams. Rails 17a, 17b are also attached to the beams and guide the objects. Other rails 18a, 18b, 19a, 19b guide the objects before and after their passage between the chains. Downstream of the conveyer 5 is provided a conveyer comprising endless chains 22a, 22b interconnected by cross bars 23. Above a roller conveyer 24 are rails 25a, 25b which realign the objects as they leave the conveyer 5. In a modification, Fig. 6 (not shown) damage to objects by the dogs is minimized by providing pivoted arms 35a, 35b which avoid direct contact with the articles by the dogs. A further modification, Figs. 7-10 (not shown) is adapted for objects fed to the apparatus in pairs abreast. In Figs. 8-10, an endless chain type of conveyer replaces the roller conveyer (5) of the previous embodiments. Additional chains (43, 44) have fingers (41, 42) for further controlling the forward travel of the objects.

Title: Improvements in or relating to the manufacture of articles of plastics using extrusion apparatus
IPC: B29C48/09
Filed: 1964-10-15
Abstract: 1,088,039. Extrusion / blow - moulding. REXALL DRUG & CHEMICAL CO. Oct. 15, 1964 [Oct. 15, 1963; June 4, 1964], No. 42160/64. Heading B5A. In an extrusion/blow-moulding process the wall thickness of the extrudate is varied in accordance with a predetermined programme by control means including a detecting element responsive to the length of the extrudate. As described the extruder head of the machine is initially closed by a mandrel 4, Fig. 2. On closure of a switch 26 an electromagnet 24 is energized to actuate a control valve 19 which controls the fluid supply to a cylinder 30 to cause upward movement of the piston block 28, 17 to pivot the lever 11 clockwise so lifting the mandrel 4 and allow plastics material to leave the extruder head and enter a raised two-part neck mould 44. The switch 26 is opened and pressurized fluid is supplied to the cylnder 50 to cause the piston 51 to move downwardly with the neck mould 44. The valve 19 is now controlled by a cam and cam follower mechanism 71, 72, acting through the linkage 20, 73, to regulate the flow of pressurized fluid to the cylinder 30 of the piston 28 and so control the position of the mandrel 4 in dependence on the position of the neck mould 44 and in accordance with the profile of the cam 71. On completion of the extrusion the switch 27 is closed, e.g. manually, by timing means or by electrically or mechanically operated sensing means, to energize the electromagnet 25 so that the valve 19 moves downwardly to cause the piston block 28, 17 to move downwardly so pivoting the lever 11 counter-clockwise and closing the mandrel 4 on the seat 6. The blow mould sections 85 and 86 are then closed on the extrudate and the blowing tube 61 is supplied with air. After blowing the blow mould sections 85, 86 are separated. The gripping device 92 is moved over the sprue tail 95 which is engaged by pivoting fingers 94. The neck mould parts 45, 46 are then separated by upward movement of the member 55, 56. The blowing tube 61 is then withdrawn downwardly by movement of the piston 64 and the gripping device 92 is retracted to withdraw the moulded article. The fingers 94 are pivoted to pull the sprue from the article. The extruder mechanism is shown in Fig. 12 and comprises one screw 111 feeding a plurality of conduits 115 leading to conduits 119 each leading to two heads 117, 118. A reservoir chamber 120 extends from each conduit 119 and contains a piston the operation of which is controlled by a device 124, 123. The provision by the capacitors or reservoirs 121 normally allows continuous operation of the screw 111 but should all the reservoirs 120 become full, all the relays 125, one of which is associated with each reservoir, are operated to effect disengagement of the coupling device 112 in the drive from the motor 113 to the screw 111.

Each element is associated with a respective lens having a source of monochromatic light at its focus. The array of lenses may form the front face 4 of a cathode-ray tube 1, the beam illuminating a selectable portion of a mask (3) having a pin-hole aperture at the focus of each lens. Alternatively the lenses may be illuminated by a laser beam. The light passing through the selected element falls on a lens 6 which focuses it on to a planar array of concentric rings of photo-cells 8, the cells being selectively energized according to the data stored in the selected element. As disclosed there may be 24 superimposed screens in each element 5a, each screen having one of three screen constants. To sense the data there are three rings of photo-cells 8, the outer ring having 2 x 12 cells, the middle ring 2 Î 8 cells, and the inner ring 2 Î 4 cells, i.e. a total of 2 Î 24 cells. Only one half of the three rings need to be used as the pattern of light from a selected element is symmetrical about one axis.

Title: Improvements in or relating to the recovery and purification of acrylonitrile
Inventor: GRICE ROY
Filed: 1963-11-02
Abstract: Acrylonitrile, especially resulting from a vapour phase catalytic reaction of propylene, ammonia and oxygen after quenching by contact with sulphuric acid at above 80 DEG  C., from a substantially ammonia free gaseous reaction product containing hydrogen cyanide and carbonyl compounds, is recovered by a process which comprises washing with water, to absorb the components, allowing the carbonyl compounds and HCN to form cyanhydrins while maintaining pH at 5 to 6.4, e.g. by adding sodium hydroxide, adjusting the pH of the resultant solution to less than 3 and separating HCN and acrylonitrile by distillation. The base residue from the distillation may be made alkaline and distilled to recover carbonyl compounds and HCN.  A flow sheet (not shown) illustrates the invention and includes provision for recirculating the wash liquor after HCN recovery.
